' TORPEDO-PROTECTING NET FOR S HIPS.

Specification of Letters Patent.

Application filed August 5, 1915. Serial No. 43,769.

To all whom it may concern:

Be it known that'I, JOHN BocNAR, a subject of the King of Hungary, residing at Renovo, in the county of Clinton and State of Pennsylvania, have invented certain new and useful Improvements in Torpedo Protecting Nets for Ships, of which the following is a. specification.

This invention relates to certain new and useful improvements in torpedo protecting nets for ships.

An object. of the present invention is. to.

provide a protecting shield for ships that will effectively prevent a torpedo from striking the ship above orbelow the water line.

A further object of the invention is to provide a torpedo net attachment for ships in which the net is composed of overlapping sections that are supported on the sides of a vessel and include floating tanks or buoys that will cause the same to assume a position adjacent the surface of the water and to rise and fall when the boat lists from side to side. i

A still further object of the invention is to provide a torpedo netfor ships in which the netted screen sections may be elevated on slotted guides to be removed from operative position in'the water'to inoperative position and be supported on the guide racks at a position located above the floating buoys and supports therefor, and it is also to be understood that the entire protecting device may be completely removed from the sides of a vessel, the same constituting a removable protecting torpedo net.

With these general objects in view and others that will appear as the nature of .the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claims. In the drawings forming-a part of this application and in which like designating characters refer to corresponding parts throughout the several views: Figure l is a top plan view of a portion of a boat with the present torpedo net in operative position thereon. Fig. 2 is a side elevational view of several of the net sections-showing the same in overlapped position. Fig. 3 is an edge view of several of the net sections in diagrammatic form, showing the overlapped position of the sections. Fig. 4 is a detail perspective view of a portion. of the side of a vessel, shown in section, with the torpedo net and supporting mechanism therefor mounted'on the side of the ship, and, Fig. 5 is a top plan view of the same.

Referring more in detail to the accompanying drawings, and particularly to Fig. 1, the reference numeral 10 designates aship carrying radial brackets 11 mounted on floats or'buoys 12 with guide frames or torpedo nets 13 carried by the outer ends of the brackets and be in overlapped position as at 14 so as to completely protect the sides and adjacent bottom portion of the ship from torpedoes. The ship 10 includes the side wall 15 which receives at suitably spaced points the clamp members 16 secured thereto by thumb screws 17 and carrying apertured hooks 18 for purposes to be later described, the said hooks being secured to the clamps 16 by the angularly-projecting lugs 19. Hanger bars 20 are supported by the clamps 16, a connecting link 21 securing the lower end of the-clamp to the upper end of the hanger bar while the faces of the hanger bar are provided with spaced openings for the reception of the angularly-projecting' 24, preferably of tubular construction as shown with spaced vertical openings 25 extending therethrough. The net supporting bracketsll as shown in Fig. 1 are more clearly shown in detail in Fig. 4, the same consisting of superposed bars 26 bolted together as at 27 and carrying supporting lugs 28 adapted to be received on the supporting rod 24 carried by the bracket 23 while a pin 29 passes through an opening in the supporting lug 28 and through a registering opening 25 in the supporting rod 24, thisv form of connection substantially locking the brackets 11 to the supporting brackets 23. A. pair of vertically alined angle brackets 30 are carried by the outer legs of the supporting bracket and bent upon itself and secured as by rivets 33, one end of the strap 32 projecting beyond the rivets 33 and having pivoted thereto on the horizontal pin 34, one link 35 of a double arm, the inner end of theother 'arm being pivotally connected thereto by the horizontal pin '36 so that the. arms 35 may be permitted to movei'na vertical direction on their horizontal pivot pins.

nected therefrom. The floats 12 are more clearly shown in Figs. 2 and 4 and include hollow air-tight bodies 42 which carry on the upper deck thereof pins- 43 of suitable construction to adapt the same to be secured to the lower connecting straps 39. A depending lug 44 is carried by the upper straps 39 and has'connected thereto one end of a cable 45 which passes through a guide ring 46 carried by the link arm 37 while the other end of the cable carries a hook 47 adapted to be received in the apertured hook 18, it being-the purpose of this cable to limit the lowering movement of the outer end of the brackets 11 and further to assist in the removal of the nets from the sides of the ship.

The construction of. the torpedo nets and the particular manner of attaching the'same to the brackets 11 is more clearly shown in Figs. 2 and 4, there being illustrateda vertical frame bar 48 angularly directedat its upper end as at 49 and slotted throughout the major portionof its length as at 50, the said bars 48 of the guides being secured as by riveting or other suitable fastening means 51 to the central portion of the bolt 40. A pair of lateral extensions 52 are carried by the central portion of the bolt 40, the said extensions being slotted .as at 53. The torpedo nets consist of rectangular frames including upper and lower horizontal bars 54, and end bars 55. Each frame carries adjacent each end thereof a second vertical end bar 56 which carries a pin'57 adapted to be received in the slot 53 of the extension 52- and retained in position by the collar 58 and set screw 59. VA wire fabric or other suitable net 60 is carried by each net frame and operates for the purpose intended.

From the above detaileddescription of the invention, it is believed that the operation thereof will be readily apparent, it being It is to be understood that these arms 35 and straps 32 are mountnoted that the brackets 11 are permitted to swing in a horizontal direction by reason of their connections on the vertical pivot bolts 31 and 40 while a vertical swinging movement is afforded by the horizontal pivotal connections 34, 36 and 38. The buoys 42 will operate to effectively hold the nets 13 adjacent the surface of the water and will rise and fall with the listing of the ship. When it is desired to remove thenets 13 from the water, the collars and set screws 58 z 1nd 59 may be removed from the slotted extensions 52, at which time. the nets may be readily moved upwardly upon the slotted guides 50 so that a comparatively small amount of resistance will be offered to the forward movement of the boat when it is desired to obtain greater speed. The complete apparatus may be removed from the sides of the ship by removing the retaining pins 29 from the supporting brackets 23 and lugs 28, whereupon the entire net mechanism may be removed, and by releasing the clamps 16, the said clamps and bar hangers 20 may be removed. It is to be noted that the apparatus is extremely simple in con: struction and easy same may be readily positioned on a ship in a comparatively short amount of time.

While the forms of the'invention .herein shown and described; are what are believed to be preferable embodiments thereof, it is nevertheless to be understood that various forms, modifications and arrangements 'of the parts may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
